Satyrium nepalense is a terrestrial medicinal orchid of the Himalayas. Although, the ecology and medicinal uses of this orchid is well known, little is known about its reproductive mechanism. In this study, we explored the natural history and reproductive biology of S. nepalense and tested their potential spatial variation. We observed the floral visitors and natural fruit set of S. nepalense at its two populations. We found that, despite the presence of outcrossing features, this orchid did not receive any diurnal floral visitors. The natural fruit set was very high (>90.0%) at both the sites, suggesting the possibility of autonomous selfing. This finding may have important implication for the further study to explore how autonomous selfing evolves in a member of the predominately outcrossing genus. Moreover, the finding of this study provides important insight to develop efficient protocol for its conservation.

The Cuban Boa (C. angulifer) is the only boid snake in Cuba. It is the largest member of the genus, as well as the largest snake in the West Indies (> 400 cm in snout-vent length); as such, it is an iconic species of the Cuban herpetofauna. Although the snake’s natural history is poorly known, several studies describe aspects of its reproductive biology in captivity. Herein we document the sizes and ages at which both sexes reach sexual maturity in nature, and show that the Cuban Boa reaches adulthood at a much smaller size than previously reported for captive snakes. Based on the limited information on the growth rate of C. angulifer in nature, males must reach breeding size after 3 years and females after 5 years

A second observation on the reproduction of Blythia reticulata was based on three eggs found on a forest path among leaf litter and successfully incubated. Given the limited knowledge on the natural history of the species, including its breeding biology, we provide information on egg measurements (n = 3; length = 25.54 ± 1.05 mm; width = 11.79 ± 0.37 mm; weight = 1.94 ± 0.24 g) and the first data on hatchling biometrics (n = 3; snout-vent length = 106 ± 1.73 mm; tail length = 14 ± 1.00 mm; weight = 1.13 ± 0.09 g) from Mizoram State, northeastern India.

Population dynamics studies raise relevant data to understanding ecological aspects and natural history of species as well as better conservation strategies. Using two scorpions species, Troglorhopalurus translucidus Lourenço, Baptista & Giupponi, 2004 and Troglorhopalurus lacrau (Lourenço & Pinto-da-Rocha, 1997) from Chapada Diamantina, Bahia state, Brazil, we estimate populacional parameters through mark and recapture methodology, and Jolly-Seber estimator. In addition, data on both species as sexual ratio, reproductive biology, growth, longevity, feeding habitats, and seasonality were analyzed in the caves and afterwards compared to other scorpion species as well as other arachnids. We captured and marked 82 specimens of T. translucidus and 65 specimens of T. lacrau. Population estimates were 361 ± 199 individuals to T. translucidus and 333 ± 252 to T. lacrau. Population estimates were considered high for the troglobitic scorpions when compared to subterranean arachnids or even with epigean species of scorpions. Both troglobitic scorpions featured remarkable differences in relation to epigean scorpions as higher longevity, longer reproductive period, slower growth. Besides T. translucidus showed marked seasonality with populational variations in rainy seasons in contrast to T. lacrau with populational stability. Suppl. material 1

A New Species

A new species of monostiliferous hoplonemertean, Tetrastemma phyllospadicola, is described from specimens collected on San Juan Island, Washington, U.S.A. The worms occur in great abundance on intertidal growths of the surfgrass Phyllospadix scouleri Hooker. The distinctive morphological characteristics of T. phyllospadicola are described, and aspects of its reproductive biology and natural history arc reported.
